dde77d1cf6 qemu: capabilities: Don't probe device properties for 'virtio-*-s390' devices
The devices no longer exist in qemu since the 2.6 release. Drop the
probing of the device properties and fix the data for
qemucapabilitiestest.

b560d1c876 qemu_capabilities: detect if confidential-guest-support is available
virQEMUCapsProbeQMPMachineProps currently skips any not supported
machine type which includes `none` as well.

In order to start probing that machine type we need to add an exception
to not skip it when probing QEMU capabilities.

fb292c659f qemu: capabilities: Probe QMP schema before probing commands
All supported QEMU versions now support query-qmp-schema. In the future
it will be possible to use the output of query-qmp-schema to also detect
commands reliably.

Since we are at the point where we have the least amount of .replies
files needing changing for a long time, move the 'query-qmp-schema' bits
before 'query-commands' to prepare for the future.

aa21615ccb tests: qemucapabilitiesdata: Fix formatting of manually added hunk
Commit 66c5674e79 added a query for the device properties of 'usb-host'
but the command header isn't formated the same way as if it were
autogenerated. Reformat all the files.

66c5674e79 qemu_capabilities: Add QEMU_CAPS_USB_HOST_HOSTDEVICE
This capability tracks whether "usb-host" device has "hostdevice"
attribute. This attribute allows us to specify full path to the
USB device ("/dev/bus/usb/$bus/$dev") but more importantly, since
QEMU uses qemu_open() for this attribute it allows us to pass
pre-opened FD and have QEMU not bother with opening the file at
all.

The attribute was added in v5.1.0-rc0~71^2~1 QEMU commit.

cbd4ab4cc6 qemu: new capabilities flag pcie-root-port.hotplug
This caps flag is set when the qemu binary supports the option
"hotplug" for pcie-root-port, ioh3420 (Intel pcie-root-port) and
xio3130-downstream (Intel pcie-downstream-port). If it's available,
it's possible to disable hotplugging/unplugging devices on a
particular port by adding ",hotplug=off" to the qemu device
commandline. This option first appears in qemu-5.0.0.

e41e3b29be qemu: Probe machine types for both KVM and TCG
Almost all TCG query-machines replies match KVM. The only exceptions are
4.2.0 replies on s390x which differ in the reported default CPU type.
